Hibiscus for high blood pressure?

I just read that drinking a tea made of hibiscus flower can lower blood pressure. I'm thinking about trying it, and was just wondering if anyone else drinks this and if it really works.
Hibiscus for high blood pressure?
A study, published in the Journal of the Science of Food and Agriculture, found the hibiscus extract significantly reduced the build up of fatty deposits in arteries and reduced blood cholesterol levels.. Although it's not yet proven enough unlike all other existing alternative medicine. You might as well try those who are already tested like Ginkgo Biloba, Red Yeast and homocysteine. Just a word of advice!
